Corrosion Protection of 3PE Pipeline Welding Joint
2017-03-27 15:14:30

     Three layers polyethylene coating(3PE) is widely used for steel pipeline in many fields such as oil,gas,water supply,chemical and so on.It is a well-know pipeline anti-corrosion coating in the world. The welding joint just the key point.Now we use heat shrinkable sleeves for the corrosion protection of the welding joint, mostly the heat shrinkable wraparound sleeves.

      Why we chose heat shrink sleeve? The heat shrinkable sleeve made of polyethylene backing and special adhesive that suitable for polyethylene jack and steel with primer.Also, Tongjin manufacture  a mastic heat shrinkable sleeves that can applied without primer , the ahesive of mastic heat shrinkable sleeves is suitable for bare steel surface. So far heat shrinkable sleeve is best choice for 3PE pipeline welding jiont because of the excellent property.
